(an input expression of type CHARACTER) is a parameter identifier, as described for AGSETP, above. If a group of more than one parameter is specified, only the first element of that group will be affected by the call.

IUSR

(an input expression of type INTEGER) is the value to be given to the parameter specified by TPGN.

To use AGSETI or c_agseti, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order. To get smoother curves, drawn using spline interpolation, also load libdashsmth.o. Or, you can use the ncargf77 command to compile your program and load the above libraries, then, to get smoother curves, use the -dashsmth option.
